Description

The present invention relates to processes and systems for manufacturing windows / doors.

As used herein, window / door means a structure intended to close an opening (window, door, wing, etc.) made in a wall, floor, or roof on the outside or inside of a building. are doing.

The structure may be mobile (eg, window wing) or fixed (firmly fixed to the wall).

Windows / doors usually consist of an outer frame made of aluminum, plastic, or other material, glass, plexiglass, or an inner panel made of other material (either transparent or opaque).

Especially in the field of windows / doors with plastic frames, these frames are made by closing a number of corresponding contour elements in one, preferably PVC or other heat sealable. It is preferably made of a plastic material.

Sealing of contour elements melts each vertex surface obtained by heating the points connected at the appropriate surface with the heating element, and presses the heated parts against each other until they are bonded to each other. It is done in.

In general, the heated portion is the head edge of the contour element, which is cut exactly at 45 ° to define something like, for example, a right angle point on the frame.

This method is implemented by a sealing machine with respective holding members of contour elements that are movable closer to each other in order to bring the heated ends into contact with each other for sealing.

Other machines are also equipped with a finishing system that can remove the bead, the sealing bead that forms between melting the two contour elements.

In fact, at the position of the line where the two contour elements (the surface is cut at 45 °) join, some of the excess molten material spills out and protrudes from the visible surface of the contour element. The bead is formed.

For this reason, once sealed contour elements go through a process for bead removal to give the finished window / door a visible aesthetic appearance.

However, the known sealing devices briefly described above have major drawbacks with respect to the formation of the sealing beads described above.

In fact, the sealing area of the plastic contour element is not perfectly homogeneous, so to make the profile regular, a large amount of material is melted, resulting in the formation of excess beads, so it should be removed. Consideration must be given to the large amount of material that must be discarded.

In addition, a finishing process suitable for removing beads and cleaning the sealed area will significantly affect the overall timing of window / door processing.

In fact, it should be recognized that for any sealing of windows / doors, contour elements must be machined thereafter.

Moreover, for rounded contour elements, bead removal is fairly complex.

In addition to this, the machinery used in the aforementioned finishing work turns out to be bulky, complex and particularly expensive.

This also requires that additional costs and processing times due to the presence of additional bulky equipment and tools be addressed.

Patent Document 1 shows a method and an apparatus capable of eliminating the above-mentioned drawbacks.

The system shown in Patent Document 1 actually has two moving holding members on which contour elements are mounted so that they can be sealed without forming any sealing beads. By applying a containment retainer juxtaposed to the heated contour element during sealing, which is adapted to form a containment compartment for the sealed bead on the contour element by prior milling of the area to be sealed. , Prevents molten material from leaking out of the containment compartment.

Several sealing methods are shown in Patent Documents 2 and 3.

Once the contour elements are sealed in one, a window / door frame is obtained, which is then completed by attaching the inner panel, as schematically shown in FIGS. 1 and 2.

The inner panel A is manually placed by an operator in a previously sealed frame B (FIG. 1).

After that (FIG. 2), the operator joins the inner panel A to the contour elements D1 and D2 of the frame B and secures it with a holding edge pressed against the inner panel A, that is, a glazing bead C.

During fixing of the glazing bead C, the operator also places the seal E between the inner panel A and the glazing bead C.

After completing this task, the glazing bead C is integrated with the window / frame and the seal E is pressed against the inner panel A to ensure its sealing.

The contour elements D1 and D2 of the frame B usually have a fairly complex cross section, but the central portion D1 is always visible and is intended to surround the inner panel A from the side. The inner panel A is placed in contact with the convex portion D2; in the solution shown in FIGS. 1 and 2, for example, the cross sections of the contour elements D1 and D2 are substantially L-shaped. , The central portion D1 and the convex portion D2 are orthogonal to each other.

The glazing bead C is attached to the central portion D1 on the opposite side of the convex portion D2 so as to surround the inner panel A like a sandwich.

The work of attaching the inner panel A to the frame B is generally called "glazing", but it has considerable drawbacks.

First of all, this task is neither very practical nor easy and must be done manually by professional personnel.

In addition to this, it is inconvenient to carry out the glazing work, occupying a large space that may be otherwise available in the door and window manufacturing plant.

As a result, the cost of performing glazing work is very high not only for labor, but also for factory management costs, which inevitably leads to higher selling prices for windows / doors, making the product less attractive to customers. there is a possibility.

The main aim of the present invention is to provide processes and systems for the manufacture of windows and doors that make it possible to obtain production systems with excellent performance and significantly lower costs.

A further object of the present invention is to make available processes and systems that greatly simplify the entire window and door manufacturing process.

A non-final object of the present invention is to provide a process and system for manufacturing windows and doors that allows them to gain a significant advantage over their competitors.

Another object of the present invention is the process of manufacturing windows and doors that are not only simple, rational, easy to use and effective, but can overcome the aforementioned drawbacks of the prior art within a range of affordable solutions. And to provide the system.

The aforementioned object is achieved by this process for manufacturing doors and windows having the features of claim 1.

The aforementioned object is also achieved by the system for manufacturing doors and windows having the features of claim 16.

With particular reference to figures such as these, the window / door obtained by combining at least one inner panel 2 for the window / door and multiple plastic contour elements 3 for the window / door is as 1 throughout. It is shown.

It is advantageous that the inner panel 2 is made of glass (single or multi-layer), but it is not possible to exclude that it can be made of either transparent or opaque plexiglass or other material. Can not.

The inner panel 2 has a plurality of peripheral side portions 4.

It is preferred that the inner panel 2 has a substantially rectangular shape, with four peripheral side portions 4 arranged at 90 ° to each other; Alternative embodiments that are shaped differently (eg, triangles, pentagons, hexagons, etc.) cannot be ruled out.

The contour element 3 is made of, for example, PVC, but similarly, a heat-sealed plastic material different from PVC cannot be excluded.

If the inner panel 2 is rectangular, the number of contour elements 3 is one for each peripheral side 4, so it is four; but for the triangular inner panel 2, there are three contour elements. It is easily understood that 3 is adopted, and in the case of the inner panel 2 of the pentagon, 5 contour elements 3 are adopted.

Each of the contour elements 3 has at least two sealed regions 5 that can be coupled to the sealed regions 5 of the other contour elements 3 so as to define the frame of the window and the door.

The sealed area 5 of the contour element 3 is cut at 45 ° to define a 90 ° bond between the two consecutive contour elements 3 so as to allow the coupling by sealing.

Each of the contour elements 3 further has at least one lengthwise slot 6 into which the peripheral side portions 4 of the inner panel 2 can be inserted.

The contour element 3 has at least a first lengthwise portion 7, a second lengthwise portion 8, and a third lengthwise portion 9 that are substantially disposed of each other in the C pattern. The first lengthwise portion 7 and the second lengthwise portion 8 extend from the third lengthwise portion 9, between which a lengthwise slot 6 is defined.

Within the scope of the present specification, the term "lengthwise" of contour elements 3 means the direction of their lengths; such contour elements 3 are long when usually made by extrusion of plastic material. The vertical direction coincides with the extruding direction.

The first lengthwise portion 7, the second lengthwise portion 8, and the third lengthwise portion 9 are formed by a single integral fuselage, i.e., directly with the contour element 3. It may be extruded through a matrix whose shape is set so as to have a C shape.

Alternatively, lengthwise contour elements 7, 8, and 9 can be made separately from each other and assembled later; for example, second lengthwise portions 8 and third lengths. The directional portions 9 are extruded together to form a single, substantially L-shaped body, while the first longitudinal portion 7 is extruded separately and, after extruding, the third longitudinal portion. Can be attached to portion 9 (eg, by concatenation).

In any case, the process and system of the present invention is a contour element in which the lengthwise portions 7, 8 and 9 are arranged in a substantially C shape prior to being sealed, defining the lengthwise slot 6. The use of 3 is provided; on the contrary, this is a very important difference compared to the traditional technique in which the contour elements are shaped into an L shape and the glazing beads are attached only after sealing.

The distance between the first lengthwise portion 7 and the second lengthwise portion 8 is set depending on the thickness of the inner panel 2; the lengthwise slot of the inner panel 2. The insertion into 6 is performed substantially exactly, as described better below.

The process of the present invention has the following steps.
Step to provide inner panel 2;
Step of providing a plurality of contour elements 3;
Steps to perform the step of machining by chip removal on at least one of the sealed areas 5;
The step of heating the sealed area 5;
A step of joining the heated sealed areas 5 to each other by keeping the sealed areas 5 in contact with each other and pressing the contour elements 3 against each other to define the window / door frame, which is the contour. The inner panel 2 is inserted into the slot 6 in the length direction so as to define the window / door 1 composed of the frame of the element 3 and the inner panel 2 contained within the frame of the contour element 3. Steps taken while you are.

In order to carry out the coupling between the inner panel 2 and the contour element 3, the process of the present invention has the following steps.
In a state where the peripheral side portions 4 are arranged so as to face the slot 6 in the length direction, the inner panel 2 is inserted so as to be substantially the same plane as the arrangement plane 10 of the slot 6 in the length direction. Steps to place;
A step of moving contour elements 3 from positions distant from each other to positions closer to each other, wherein the movement is adapted to insert the inner panel 2 into the slot 6 in the length direction.

The step of joining the contour elements 3 is substantially performed by pressing all the contour elements against each other at the same time.

In other words, at the time of joining, the inner panel 2 is located in the insertion configuration, and at the same time, all four corners of the frame of the contour element 3 are joined at 90 °, and the sealed area of the contour element 3 is sealed. All of 5 are pressed into one against each other.

The step of performing machining by chip removal is performed, for example, prior to the step of heating by a suitable removing means 44.

The removing means 44 is, for example, a milling cutter.

The step of performing machining by chip removal includes the step of forming a groove 11 (shown in FIG. 3) at the position of at least one sealed region 5 of the contour element 3 and coupling the sealed regions 5. The steps to be performed include a sub-step in which the sealed area 5 between them is melted to determine a sealed bead, and a sub-step in which a containment compartment defined by the groove 11 is formed and the sealed bead is formed inside the containment compartment. It is convenient to do.

The step of forming the groove 11 is preferably implemented by the work of tip removal on the peripheral edge of at least one contour element 3.

It is convenient that the groove 11 can be realized on the contour element 3 as taught by Patent Documents 1, 2 and 3.

It is advantageous that the removing means 44, in addition to or instead of creating the groove 11, can have all or part of the sealed area 5 at the same depth.

When the groove 11 is present, for example, the removing means 44 can make the non-existent portion of the groove itself in the sealed region 5 the same depth.

In that case, the removing means 44 can be passed through substantially the entire sealed region 5 at various processing depths below.
At the edge position of the sealed area 5, the processing depth of the removing means 44 is deeper, the depth that defines the groove 11.
In the rest of the sealed area 5, the processing depth of the removing means 44 is shallower, removing only a small layer of plastic material sufficient to flatten the sealed area 5 to the same depth. That's right.

In other words, the removing means 44 is not only used to form the groove 11, but is also absolutely essential to make the walls the same depth and correct any cutting errors.

The groove 11 can be realized by all the lengthwise portions 7, 8, and 9 of the contour element 3, or can be realized by only some of them.

In a possible embodiment of the invention, for example, the groove 11 is realized only in the second lengthwise portion 8 and the third lengthwise portion 9, whereas in the first lengthwise direction. The portion 7 is completely set to the same machining depth corresponding to the machining depth of the groove 11.

Thus, the contour element 3 does not heat the first lengthwise portion 7 and does not melt during the bonding step and is substantially close to it, whereas the second lengthwise portion 7 It is intended that the portion 8 and the third longitudinal portion 9 are melted and bonded together to be sealed together.

The heating step comprises, for example, at least a sealing element comprising a heated plate having two facing surfaces capable of contacting and arranging the two sealed areas 5. It is advantageous that it is done by the heating means 13.
The sealing element comprising the heated plate 13 comprises, for example, a heating element having a substantially plate-like morphology.

In fact, the sealed area 5 is heated by bringing the contour element 3 closer from the opposite side and pressing it against the surface of the sealing element 13 comprising the heated plate.

During the heating step, it is preferred that a plurality of sealing elements comprising the heated plate 13 be used at each corner of the frame of the contour element 3.

In the particular embodiment shown in FIGS. 3-6, the heating step is performed with the inner panel 2 located outside the lengthwise slot 6 and is coupled with the heating step. In the meantime, less than 2 seconds of coupling time elapses while the inner panel 2 is inserted into the slot 6 in the longitudinal direction.

In this embodiment, while the inner panel 2 is not in the insertion configuration, the sealed regions 5 face each other 2 to 2 and the longitudinal slots 6 are 2 to 2 as shown in FIG. The contour element 3 is first placed in substantially the same plane in a state of being oriented so as to face each other.

The contour elements 3 are held apart from each other, and between the sealed areas 5, a sealing element 13 with a heated plate is placed, substantially facing the corresponding sealed area 5. They are arranged in parallel with each other, and therefore are inclined by 45 ° with respect to the direction in the length direction of the contour element 3.

By simultaneously approaching the sealing element 13 with the heated plate, the contour element 3 contacts the sealing element 13 with the heated plate for heating; the contour Element 3 moves along a direction orthogonal to the contour element itself (FIG. 4).

At this point, the contour element 3 is moved away, the sealing element 13 with the heated plate is removed, and the inner panel 2 is substantially on the placement plane 10 of the slot 6 in the longitudinal direction. It is placed in an insertion configuration that is flush with each other (Fig. 5).

The contour elements 3 that are distant from each other are finally moved to a position that is close to each other; this displacement first inserts the inner panel 2 into the slot 6 in the longitudinal direction and finally seals. The regions 5 are arranged side by side and pressed against each other (FIG. 6).

The heating step ends the moment the contour element 3 separates from the sealing element 13 with the heated plate, whereas the moment the heated sealed area 5 comes into contact, vice versa. , The joining step begins.

At the time of joining, it becomes as follows.
The sealing element 13 with the contour element 3 and the heated plate must be separated;
The inner panel 2 should be placed in the insert configuration;
The contour element 3 must be reapproached until the sealed areas 5 are placed in contact with each other in order to insert the inner panel 2 into the lengthwise slot 6.

If the bond time is less than 2 seconds (more specifically less than 1 second, preferably equal to about 200 ms), the above-mentioned operation is to overcool the heated sealed area 5 before contacting it. And run fast to avoid jeopardizing their binding.

In the alternative embodiments shown in FIGS. 7 to 10 in order to reduce the implementation time and slow down the speed of movement of the contour element 3, the inner panel 2 is at least after the machining step by chip removal. The heating step is performed in a state where it is arranged so as to be partially inserted inside one lengthwise slot 6, and at least one step is performed between the heating step and the joining step. A coupling time of less than 2 seconds elapses from the position where the contour element 3 corresponding to the slot 6 in the length direction is partially inserted to the position where it is completely inserted.

During the heating step, the inner panel 2 is arranged such that it is partially inserted into slots 6 in all length directions, in other words, all contour elements 3 are partially inserted. It is convenient to put them in the inserted position at the same time.

The contour element 3 is initially arranged in exactly the same manner as the embodiment shown in FIG. 3, that is, the sealed regions 5 face each other 2 to 2 and the slot 6 in the length direction. Are placed substantially coplanar with the two-to-two oriented facing each other; on the other hand, the inner panel 2 is placed in an insert configuration, unlike what occurred in the previous embodiment. ing.

In the embodiments shown in FIGS. 7-10, the sealing element 13 comprising a heated plate is at least partially complementary to the cross section of the inner panel 2 and is at least partially complementary to the inner panel 2. It has at least a recess 14 that can be arranged so as to at least partially enclose the peripheral side portion 4 of the.

At the location shown in FIG. 7, all sealing elements comprising the heated plate 13 are arranged so as to partially enclose the peripheral side 4 of the inner panel 2, in particular its corners. There is.

The contour elements 3 are held apart from each other, and between the sealed areas 5, a sealing element 13 with a heated plate is placed, substantially facing the corresponding sealed area 5. They are arranged in parallel with each other, and therefore are inclined by 45 ° with respect to the direction in the length direction of the contour element 3.

When the contour element 3 simultaneously approaches the sealing element 13 with the heated plate, the contour element 3 is first in the position of partial insertion, and in fact, the peripheral side 4 of the inner panel 2 is , Partially inserted into slot 6 in the length direction, and then pressed for heating so that the sealed area 5 contacts the sealing element 13 with the plate being heated; contour The movement of the element 3 is also performed along the direction orthogonal to the contour element itself (FIG. 8).

At this point, the contour element 3 moves slightly away from the sealing element 13 with the heated plate, still fitted around the peripheral side portion 4 of the inner panel 2.

Therefore, the sealing element 13 with the heated plate is tilted at 45 ° with respect to the contour element 3 and along a direction coplanar with the sealing element 13 with the heated plate. By sliding, it moves away from the contour element 3 and the inner panel 2 (FIG. 9).

The contour element 3, which is still in a partially inserted position, finally approaches until the sealed area 5 is placed in the position of a complete insertion that is juxtaposed and pressed against each other for coupling (FIG. 10). ).

The heating step ends the moment the contour element 3 separates from the sealing element 13 with the heated plate, whereas the moment the heated sealed area 5 comes into contact, vice versa. , The joining step begins.

Then, at the time of joining, the inner panel 2 is already located in the insertion configuration, and the stroke in which the contour element 3 must move is the stroke in which the contour element 3 shown in FIGS. 3 to 6 must move. It will be significantly shorter than.

In a further embodiment shown in FIGS. 11-15, for which, after the machining step by chip removal, the inner panel 2 is completely inserted inside at least one lengthwise slot 6. The heating step is performed while being arranged so that, and between the heating step and the joining step, there is an inner panel with contour elements corresponding to at least one lengthwise slot 6. Less than 2 seconds of binding time elapses with respect to 2 that is substantially stationary, i.e., staying in the fully inserted position.

More specifically, in this case, the contour elements face the pair of first contour elements 3a located on the side facing the inner panel 2 and the inner panel 2. It is convenient to be divided into a pair of second contour elements 3b that are similarly arranged on the side of the surface; if considered without distinction from each other, the first contour elements 3a and the second contour. Element 3b is commonly represented by reference number 3.

During the heating step, the inner panel 2 is completely inserted into the lengthwise slot 6 of the first contour element 3a and partially into the lengthwise slot 6 of the second contour element 3b. It has been inserted.

In other words, once placed on the inner panel 2, the first contour element 3a is immediately placed at the full insertion position and no longer moves; in contrast, the second contour element. The 3b can first be placed at the partial insertion position and then only at the full insertion position.

The contour element 3 initially has an aspect exactly similar to that of the embodiment shown in FIG. 7, that is, the inner panel 2 is in an insert configuration, whereas the sealed regions 5 face each other 2 to 2. The slots 6 in the length direction are arranged in substantially the same plane in a state where they are oriented so as to face each other in a 2 to 2 direction.

Also in the embodiments shown in FIGS. 11 to 15, the sealing element 13 with the heated plate is at least partially complementary to the cross section of the inner panel 2 and is at least partially complementary to the inner panel 2. Although it has at least a recess 14 that can be arranged to at least partially enclose the peripheral side portion 4; at the starting position shown in FIG. 11, a seal with all heated plates. The elements 13 are separated and spaced apart from the inner panel 2.

The first contour elements 3a are first moved along directions orthogonal to them until they reach the full insertion position so that the contour elements 3 are sealed around the inner panel 2. Bring them closer (Fig. 12).

At this point, the sealing element 13 with the heated plate is placed in contact with the sealed area 5 of the first contour element 3a and the second contour element 3b is hermetically sealed. The region 5 to be formed is also approached until it is placed on the sealing element 13 with the heated plate.

The displacement of the second contour elements 3b is along a direction orthogonal to them and will fit them into the corresponding peripheral side portions 4 until the position of the partial insertion is reached.

By contacting and holding the contour element 3 in contact with and holding the sealing element 13 with the heated plate, all sealed areas 5 can be heated simultaneously (FIG. 13).
At this point, the second contour element 3b is moved away from the sealing element 13 with the heated plate; depending on how long the process of moving it away is, the second contour element 3b. Can be pulled out completely from the inner panel 2 or left fitted around the peripheral side portions 4 of the inner panel 2.

Then, the sealing element 13 with the heated plate is first slid along a first direction parallel to the first contour element 3a in order to move it away from the first contour element 3a. By moving and then sliding along a second direction in parallel with the sealing element 13, which is tilted 45 ° with respect to the first contour element 3a and has a heated plate. , Moved away from the contour element 3 and the inner panel 2 (FIG. 14).

Once the sealing element 13 with the heated plate is pulled out, the second contour element 3b is juxtaposed with their sealed region 5 with the sealed region 5 of the first contour element 3a. Finally close to each other until they are placed in full insertion positions that are pressed against each other for binding (Fig. 15).

In the embodiments shown in FIGS. 11-15, the heating step moves the second contour element 3b away from the sealing element 13 with the heated plate to bring the heated plate away. The provided sealing element 13 ends the moment it is moved away from the first contour element 3a; whereas the joining step begins the moment the heated sealed regions 5 come into contact with each other. ..

Therefore, even in the embodiments shown in FIGS. 11 to 15, the inner panel 2 is already located in the insertion configuration at the time of joining, and the process in which the contour element 3 must move is shown in FIGS. 3 to 6. The contour element 3 shown is clearly shorter than the stroke that must be moved.

In all the embodiments shown in FIGS. 3 to 15, the contour element 3 is attached to at least one of the first lengthwise portion 7 and the second lengthwise portion 8. It has a sealing element 15.

In particular, a sealing element 15 consisting of a cover of rubber or other similar material is attached to a first lengthwise portion 7 along its one lengthwise edge.

During insertion into the lengthwise slot 6 of the inner panel 2, the peripheral side 4 slides into the contour element 3 and the sealing element 15 is the sealing element 15 on the surface of the inner panel 2. Allows sliding by slow movement.

In particular, if the sealing element 15 is present on the contour element 3, but not only in this case, the process of the present invention is to facilitate insertion of the inner panel 2 into the lengthwise slot 6. It is convenient to be able to provide an additional step in separating the first longitudinal portion 7 and the second longitudinal portion 8, that is, moving them slightly apart from each other.

In the pulling step, a suction element 16 such as a suction cup is applied to the first lengthwise portion 7 and / or the second lengthwise portion 8 outside the lengthwise slot 6, and the first. It is performed by applying a force 17 directed in the direction of pulling the lengthwise portion 7 and the second lengthwise portion 8 to the suction element 16 (FIG. 16).

Instead, the pulling step is performed by introducing the pulling element 18 into the slot 6 in the length direction.

The pull-off element 18 can be placed in an actuating position that pushes the first lengthwise portion 7 and the second lengthwise portion 8 in a moving direction away from each other (FIG. 17) and is an inner panel. When 2 is inserted into the lengthwise slot 6, they are peripheral to a non-actuated position that stops pulling the first lengthwise portion 7 and the second lengthwise portion 8 apart. Pushed by the side 4 of the.

The pulling element 18 is not removed from the contour element 3 and is intended to remain trapped inside the window / door 1.
Alternatively, or in combination with the sealing element 15 attached to the contour element 3, the sealing element 15 attached to the peripheral side portion 4 of the inner panel 2 can be provided.

FIG. 18 shows the inner panel 2 along the lateral side portion 19 of the peripheral side portion 4 with the intention that the sealing element 15 faces the third longitudinal portion 9 of the contour element 3. It shows an embodiment that is exactly attached to.

Therefore, the sealing element 15 is completely enclosed in the slot 6 in the length direction when the contour element 3 is sealed in one.

19 and 20 provide an additional step in interposing at least one special sealing element 15 between at least one contour element 3 and at least one peripheral side portion 4. Further modifications of the process of the present invention are shown, in which the sealing element 15 is shaped as follows.

The sealing element 15 has at least a first lengthwise band 20 that can be interposed between the first lengthwise portion 7 and the inner panel 2. The cross section of the band 20 in the direction is divided into the following sections.
With at least the first base compartment 21 adapted to remain attached to the inner panel 2;
At least the first sealing section 22 projecting with respect to the first base section 21 and having a first sharp edge 22a and a first working edge 22b, wherein the first sealing section 22 is. The first base in a manner movable between a resting position where the first sharp edge 22a is away from the inner panel 2 and an operating position where the first sharp edge 22a rests on the inner panel 2. Coupled to the compartment 21, insertion into the longitudinal slot 6 of the inner panel 2 brings the first working edge 22b into contact with the first longitudinal portion 7 and the first sealed compartment 22. Is adapted to move from the dormant position to the operating position.

The sealing element 15 has at least a second longitudinal band 23 that can be interposed between the second longitudinal portion 8 and the inner panel 2, and a third longitudinal portion 9 and the inner side. It is advantageous to also have at least a third lengthwise band 24 that can intervene with the panel 2.

The band 20 in the first length direction, the band 23 in the second length direction, and the band 24 in the third length direction are substantially arranged in a C pattern, and are arranged on three surfaces. That is, it is intended to be fitted so as to cover a part of the two main surfaces 25 of the inner panel 2 and the side portion 4 around the inner panel 2 on the lateral side portion 19.

In particular, the width of the band 24 in the third length direction is substantially equal to the thickness of the inner panel 2 so that the sealing element 15 wraps the peripheral side portion 4 substantially snugly.

The band 23 in the second length direction is substantially the same as the band 20 in the first length direction, and it is convenient because the cross section is actually divided into the following sections.
With at least a second base compartment 26 adapted to remain attached to the inner panel 2;
At least a second sealing section 27 projecting with respect to the second base section 26 and having a second sharp edge 27a and a second working edge 27b, the second sealing section 27. The second base in a manner movable between a resting position where the second sharp edge 27a is away from the inner panel 2 and an operating position where the second sharp edge 27a rests on the inner panel 2. Coupling to compartment 26, insertion of the inner panel 2 into slot 6 in the lengthwise direction causes the second working edge 27b to contact the second lengthwise portion 8 and the second sealing compartment 27. A second sealing compartment 27 adapted to move from the dormant position to the operating position.

In fact, the first base section 21 and the second base section 26 constitute a fixed portion of the sealing element 15, which, once fitted on the main surface 25, thanks to the C-shape of the sealing element 15. This is because it cannot be moved with respect to the inner panel 2.

When the inner panel 2 is inserted into the lengthwise slot 6, the first lengthwise portion 7 and the second lengthwise portion 8 are, however, the first lengthwise band. Since the displacement of the sealing element 15 is prevented by the presence of the third length band 24 holding the 20 and the second length band 23 in one, the sealing element 15 is not moved. It slides on the sealing element 15.

Therefore, the embodiments of the present invention shown in FIGS. 19 and 20 are very advantageous because the sealing element 15 is attached to the inner panel 2 without even using an adhesive material such as glue.

However, the band 20 in the first length direction and the band 23 in the second length direction are bonded to the inner panel 2 by gluing, and the sealing element 15 has the band 24 in the third length direction. It is not possible to rule out alternative embodiments of the invention that may not be.

Further, the sealing element 15 does not have both the band 23 in the second length direction and the band 24 in the third length direction, and is glued to the inner panel 2 in the first length direction. It is not possible to exclude an alternative embodiment of the present invention having only the band 20 of the present invention.

The first sealing section 22 and the second sealing section 27 constitute a movable portion of the sealing element 15, which is the moment the inner panel 2 is inserted into the lengthwise slot 6. This is because it moves from the rest position to the operating position.

For this purpose, the first working edge 22b and the second working edge 27b correspond similarly inclined on the first lengthwise portion 7 and the second lengthwise portion 8. It consists of an inclined surface intended to come into contact with the working surface 28.

The surface that identifies the first working edge 22b and the second working edge 27b is preferably 20 ° to 40 ° with respect to the arrangement plane 10 identified by the slot 6 in the longitudinal direction when the inner panel 2 is inserted. Is tilted by 30 °, whereas the working surface 28 is tilted by 10 ° to 30 °, preferably 20 °.

When the working surface 28 comes into contact with the working edges 22b and 27b, the sharp edges 22a and 27a are placed on the inner panel 2 and pushed to move the sealing compartments 22 and 27 from the resting position to the working position. ..

This particular solution ensures that the sealing element 15 is sealed against both liquids and dust and debris, so that they cannot pass through the sealing element 15 at all.

With respect to the manufacture of windows / doors 1 in accordance with the provisions of the process described above, the present invention also relates to a system 29 intended for this purpose.

The gripping device 36 is mounted on the framework 35 in a sliding manner, and the gripping device itself is only along the vertical direction 43 so that the inner panel 2 can be centered with respect to the position of the sealing machine 31. Instead, it is convenient to be attached to a trolley device 39 that allows movement along two horizontal directions 40 and 41 that are orthogonal to each other.

The trolley device 39 also aims to allow the inner panel 2 to be removed from the storage 42.

In this regard, the system 29 is located on the ground next to the base frame 30 and also has at least one storage 42 for accommodating a plurality of inner panels 2 below the frame 35. Cage; In this way, the gripping device 36 can be slid along the framework 35 and moved from the storage 42 to near the base frame 30 and vice versa.

Therefore, it is easily understood that the support assembly 34 is adapted to move the inner panel 2 from the storage 42 to the insertion configuration.

To facilitate the movement of the inner panel 2 near the sealing machine 31, the elevating means 35, 36, and 37 may have at least one mounting base 37 for the inner panel 2 to be machined. can.

In particular, the mounting base 37 is substantially located in the vicinity of the base frame 30 and is housed below the placement plane 10 in the space partitioned by the sealing machine 31.

The mounting base 37 is also elevating and can be used to move the inner panel 2 to the height of the placement plane 10 instead of the gripping device 36.
In other words, the gripping device 36

The inner panel 2 is removed from the storage 42 and placed on the mounting base 37, and the inner panel 2 is used to maintain a height below the height of the placement plane 10 and to be lifted only when necessary. be able to.

It is easily understood from the previous description of the process of the present invention that the operation of the system 29 can be implemented by the system itself.

The operation of a schematic and simplified embodiment of the system 29 is shown in FIGS. 23-25, where the system 29 has the specific type of contour element 3, inner panel 2, and seal shown in FIGS. 19 and 20. Used to work on element 15.
In this case, the inner panel 2 arrives at the system 29 with the sealing element 15 already fitted, and once gripped by the gripping device 36, is carried near the sealing machine 31 and the contour element 3 is Already mounted, secured by the associated holding member 32, and performing a machining step by chip removal using the removing means 44 (FIG. 23).

Therefore, the system 29 operates automatically to first place the inner panel 2 in the insert configuration (FIG. 24), then bring the contour element 3 closer to the inner panel 2 and the peripheral side 4 to the sealing element 15. By inserting the holding member 32 into the slot 6 in the length direction together with the sliding means 33, the holding member 32 is moved along the sliding means 33 (FIG. 25).

It was actually found that the described invention achieved the intended purpose.

In this regard, in a single work station, the frame is already sealed around the inner panel by a particular solution that provides a system with the process of the present invention and a chip removing means and a support assembly. It is clearly shown that a ready-finished window / door can be manufactured that does not require a subsequent finishing process for the removal of the sealed beads, ie "glazing" work.

The contour element is actually machined by a removal means on the sealing machine to achieve a beadless seal of the contour element performed directly along the perimeter of the inner panel.
